Description

Alaks MS330 Shock Stopper (Buffer)  For AS55 Aluminium Sliding System

Silent Closing, Extended Hardware Life

The Alaks MS330 Shock Stopper is a small yet carefully engineered component designed specifically for AS55 aluminium sliding door and window systems. Installed at the end of the sash travel path, it is positioned exactly where the highest impact, pressure and stress occur when the sliding sash is closed. Whenever you hear a sudden, annoying “bang” when closing a sliding door or window, this is the component that makes the difference: the MS330 Buffer absorbs the impact energy and prevents shock from being transmitted to the profile and hardware.

Why is the MS330 Buffer Essential for the AS55 System?

In aluminium sliding systems such as AS55, smooth operation, silent closing and stable adjustment do not depend only on the quality of the profile or glass. Standard-compliant hardware – and especially the right shock stopper – is the key factor for long service life and trouble‑free performance of the entire system.

Correct installation of the MS330 at the end of sash travel ensures:

• Prevention of sudden sash collision with the frame
• Absorption of closing impact before it reaches the lock and handle
• Smooth, quiet and low‑vibration sliding operation
• Reduced pressure on the lock, handle, rollers and track
• Significantly extended lifespan of sensitive hardware and the AS55 aluminium profile

In sliding doors and windows that are opened and closed dozens of times a day, the absence of a standard shock stopper like MS330 means repeated, destructive stress on every component in the system – which inevitably leads to higher repair and re‑adjustment costs in the future.

Material & Build Quality of the MS330 Shock Stopper:

The MS330 is manufactured from high‑grade polymer compounds specially developed for use in aluminium sliding systems. These materials:

• Provide high mechanical resistance to repeated impact and pressure
• Resist wear, crushing and early deformation
• Maintain their elasticity across the usual building temperature range (seasonal heat and cold)
• Do not dry out, become brittle or crack
• Fit securely in the AS55 designated position and remain firmly in place

In contrast, low‑grade or generic stoppers quickly crush, do not seat properly on the rail, dry out under summer heat and lose their shock absorption capacity. The result is the return of sash banging and progressive damage to the hardware.

Key Advantages of the MS330 in the AS55 Sliding System:

• Dedicated design for AS55

The dimensions and geometry of the MS330 shock stopper are optimised for the AS55 aluminium sliding system, allowing standard, precise installation without any modification to the rail or profile.

• Longer life for locks, handles, rollers and tracks

By absorbing a major portion of the closing impact, the MS330 reduces stress on the lock and other components, multiplying the service life of the hardware.

• Silent operation and smooth sash movement

With the MS330 in place, the disturbing “clack” at the end of travel is eliminated, and sash closing becomes smoother and more controlled.

• Fast and simple installation for fabricators

The location and dimensions are designed so that technicians and fabricators can install it in a very short time on AS55 systems, without special tools or structural modifications.

• Suitable for a wide range of building projects

From new residential units to renovation projects, office buildings and large‑scale developments, wherever the AS55 aluminium sliding system is installed, the MS330 is the ideal shock stopper.

Application of the MS330 Shock Stopper in Building Projects:

The MS330 has been developed specifically for sliding systems using AS55 profiles, and is used in:

• Newly built apartments with AS55 aluminium sliding windows
• Renovation projects where existing AS55 sliding systems need performance upgrade and reduced wear
• Office units with high opening/closing frequency
• Large‑scale developments where controlling maintenance and after‑sales costs is critical

This model installs in its standard seat without any modification to the rail, profile or other hardware, and is immediately ready for use.

Technical Specifications:

• Model: MS330
• Compatible system: AS55 aluminium sliding system
• Material: Wear‑resistant technical polymer
• Colour: Black
• Application: Interior and exterior aluminium sliding doors and windows

The MS330 shock stopper is not an extra cost – it is a smart investment. The cost of replacing locks, tracks, rollers and even re‑adjusting sashes is far higher than the price of a standard shock stopper like the MS330.

By choosing and installing this stopper in the AS55 sliding system you will:

• Prevent premature wear of system components
• Reduce periodic service and repair requirements
• Increase end‑user satisfaction thanks to smooth and silent operation

If you are looking for a simple yet highly effective way to extend the life and enhance the performance of the AS55 aluminium sliding system, the MS330 should be one of the key items on your hardware list.

FAQs:

1. What exactly does the MS330 shock stopper do?

The MS330 is installed at the end of the sliding sash travel. When the door or window is closed, it absorbs the impact energy, preventing direct collision of the sash with the frame and protecting the lock, handle, track and rollers in the AS55 system.

2. Is the MS330 only for the AS55 system?

Yes. This model is specifically engineered for the AS55 aluminium sliding system, with dimensions matched to its profile and design. Using it in other systems requires checking dimensions and installation seat.

3. Is installation of the MS330 difficult?

No. Installation is very simple and quick, typically by push‑fit or placement into the standard AS55 seat. Sliding system fabricators can install it without special tools; only basic tools such as an Allen key may be needed depending on the configuration.

4. When should a sliding window shock stopper be replaced?

If you hear banging when closing the sash, or if the sash seems to hit the frame too hard, the stopper has likely lost its absorption capacity and needs replacement. Visible crushing or cracking are also clear signs.

5. How does stopper quality affect hardware life?

A high‑quality stopper like the MS330 absorbs impact efficiently, reducing the load on the lock, handle, track and rollers. This slows down wear and significantly lowers maintenance costs.

6. Can the absence of a stopper damage the lock?

Yes. Without a proper stopper, impact forces are directly transferred to the lock mechanism and handle when closing the sash, leading over time to malfunction or misalignment.
